Dapper - a simple object mapper for .Net

Dapper .NET 是 .NET 下一个简单的对象关系映射库 (ORM)。

示例代码：

public class Dog
{
    public int? Age { get; set; }
    public Guid Id { get; set; }
    public string Name { get; set; }
    public float? Weight { get; set; }

    public int IgnoredProperty { get { return 1; } }
}            
            
var guid = Guid.NewGuid();
var dog = connection.Query<Dog>("select Age = @Age, Id = @Id", new { Age = (int?)null, Id = guid });
            
dog.Count()
    .IsEqualTo(1);

dog.First().Age
    .IsNull();

dog.First().Id
    .IsEqualTo(guid);
